Blazor Floating Label Overview

The Blazor FloatingLabel component provides additional features and improved user experience, compared to the standard HTML label. The floating label displays on top of empty non-focused components and moves above them on focus.

The FloatingLabel component is part of Telerik UI for Blazor, a professional grade UI library with 110+ native components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial.

Benefits

The Telerik FloatingLabel enhances HTML label functionality in the following ways:

• built-in animations
• integration with form validation
• integration with the placeholder attribute
• association with non-form elements - for example, the TelerikDropDownList component renders as a <span>

Creating Blazor FloatingLabel

1. Use the TelerikFloatingLabel tag.
2. Set the Text parameter of the floating label.
3. Place a compatible Telerik component inside the floating label.
4. Set an Id to the Telerik component. The Id value will automatically render as a for attribute for the <label> element.

How to use a Floating Label

<TelerikFloatingLabel Text="Your Name">
    <TelerikTextBox Id="name" @bind-Value="@Name" />
</TelerikFloatingLabel>

@code {
    string Name { get; set; }
}

Compatibility

The FloatingLabel integrates with focusable Telerik Blazor components:

• AutoComplete
• ComboBox
• DateInput
• DatePicker
• DateTimePicker
• DropDownList
• MaskedTextBox
• MultiSelect
• NumericTextBox
• TextArea
• TextBox
• TimePicker

The FloatingLabel does not support third-party components and generic HTML inputs.

Forms and Validation

The FloatingLabel can change its styles, based on validation state. See Validation for details and example.

Placeholder Behavior

Labels and placeholders serve similar purpose for the user experience.

If a Telerik component has both a Placeholder and a floating label, the behavior is:

• When the floating label is over the component, then the placeholder is not rendered.
• When the floating label is outside the component and the focused component has no value, the placeholder is visible.

Integration with Prefix Adornment

When using the PrefixTemplate for a component wrapped in a FloatingLabel, the label will overlap the prefix.

To ensure both the FloatingLabel and the prefix content are properly displayed, move the label with CSS:

<style>
    .custom-label-class .k-floating-label {
        margin-left: 30px;
    }
</style>

<TelerikFloatingLabel Class="custom-label-class" Text="Enter email">
    <TelerikTextBox @bind-Value="@TextValue"
                    Width="300px">
        <TextBoxPrefixTemplate>
            <TelerikSvgIcon Icon="@SvgIcon.Envelop" />
        </TextBoxPrefixTemplate>
    </TelerikTextBox>
</TelerikFloatingLabel>

@code{
    public string TextValue { get; set; }
}

FloatingLabel Parameters

The following table lists the FloatingLabel parameters. Also check the FloatingLabel API Reference for a full list of properties, methods and events.
